10 Kohler Gen in 370 Carver Aft Cabin

In mine I was able to take the gen out with 3 people fairly easily. Its interesting you have a 10KW gen in that boat though, Gas or Diesel?

Mine came right out of the hole in the salon floor and up and out the cabin doors.

Start stripping the Jewellery first, then heavier stuff next...till it comes out.

This may sound stupid, but does it have a sound shield around it and are you trying to remove it with the sound shield in place?

I would build something so the generator will sit on . Fasten to a 3/4 in pylwood. Have strong handle on all 4 corners and walk it up the stairs.Make sure everything can get threw the door.Looks like it weighs 447 LBS thats 223 lbs with 2 guys , I would have 4 guys there .

I don't mean to be mean here, but,,,
Are you doing this on your own or, are you at a yard? A service yard? A yard that has done this before?
If your putting your own time and back into this, Tear that sucker down to pieces. Little pieces.
Next bunch of silly questions, Who is putting the next unit in? Yard? Full service yard?
To honor warranties, You (yourself, personal) can not tear much down.

There could be a big point here, service yards get paid to use the proper equipment, remove and install equipment with out (imagine that) damaging your boat. Install equipment within warranty guidelines.
What may sound like a cheap plan, may just be that. A proper plan may cost more up front but protect your investment better.

Next thought
Your rebuilding a gas gen-set? Do you run your gen-set often?
Consider this;
A properly maintained diesel gen-set will out last a gas model.
A newer model diesel Gen-set may weigh less and take up less room.
A diesel gen-set is safer in several ways.
Dual fuel system is not unheard of.

More thoughts
Do you need a gen-set?
Batteries and inverters are getting better every day.

I did mine last year I took out my genny Replace the wood that supported the genny with starboard. Took my genny to a repair shop that can repair it. His charge was not bad at all put the jenny back it was done in no time at a price tag of about $600. What is wrong with yours, generators last a long time.

It's diesel. Pick up a carry tank, pre-made or make your own. You can stow diesel below decks. 10 kw diesel is going to burn 1/4 gal / hr.

Off road diesel is cheap and your burn is a fraction of what your burning now.

On a couple of my other post, I'm a big , BIG fan of safety and CO. If your into gen-sets and like to go vertical in the morning, you may want to look again at a diesel gen-set.

Keep us all updated on your final and send pictures. We all like to see other installations, big & small.

I am not an expert, so please confirm this:

I am pretty sure, You cannot put a diesel generator in the same Engine Room as a gas engine or compartment as a gas fuel tank.....

believe it or not, most diesel generators are not ignition protected....because they dont have to be.

On a diesel generator, the starter and alternator will not have the "screens" that are in gas engines protecting them from ignition of explosive gasoline vapors.

If your engine room is under the salon and your generator is under your cockpit you may be ok as long as you dont have gasoline tanks in the same compartment.

I guess you could make a box or sound shield around a diesel generator that would comply w ABYC standards....

I would recommend getting a surveyor and your insurance company to approve if you put a diesel generator in a gas boat.

It would be scary for any sparking device to be in any closed area. Gas or diesel driven. Most come covered but if not, easy to fix.
Consulting a surveyor is a great idea. He would have access to ABYC and other building guides.
I would be very interested on what ABC says about introducing a diesel appliance into a gas environment. I don't think much if anything new over any other installation. Probably painting and labeling the support lines and hoses different.

Think safe and go like Kirk.

10 KW will burn more than a 1/4 gall per hr when loaded,,try .75..

Also, mixing two different fuel engines in the same boat is not really a good idea, one moment of forgetfulness and bingo, up she could go...gas is gas and diesel is diesel, never the two should meet...

All electrical components in a compartment with a gasoline engine or fuel tank must be ignition protected. Also, the ventilation requirements for compartments containing gasoline engines or tanks must be met.

There is no law against mixing gas and diesel powered equipment on a boat, but the gasoline standards must be met unless the the diesel bits are located in separate compartments from the gasoline bits.

With gas engines I doubt the fuel savings on a diesel gen would be worth the expense and trouble. You also have to keep track of the separate diesel fuel suppply level. There's also the matter of pumping 2 types of fuel while at the fuel dock. People will love you gloming 2 fuel pumps on a Saturday morning. Again there is nothing insurmountable, but is it worth it? Personally I'd stick with gas running off the same tanks. Easier to pump, easier to keep track of and you're already set up for it.

10KW sounds like overkill. I have a 7.2 KW and it is plenty for my 370.
